Damping of liquid sloshing by foams: from everyday observations to liquid transport
We perform experiments on the sloshing dynamics of liquids in a rectangular container submitted to an impulse. We show that when foam is placed on top of the liquid the oscillations of the free interface are significantly damped. The ability to reduce sloshing and associated splashing could find applications in numerous industrial processes involving liquid transport. When a container is set in...
متن کاملInstabilities in liquid foams{
Instabilities play a central role in the physics of foams. Some that change the topology of a dry foam are indicated by the laws promulgated by Plateau in his 1873 book. Their occurrence is less clearly predictable in wet foams. Various other instabilities are related to gravitational loading and gas compressibility. We gather up many examples as a guide to future research and identify problems...
متن کاملProcessing of NiTi Foams by Transient Liquid Phase Sintering
Porous NiTi was produced by sintering pre-alloyed NiTi powders (with small Ni addition to form Ni-rich composition) with NaCl powders which are removed to create 40-60 vol.% macropores which are open to the surface, blocky in shape, and 100-400 lm in size. The microporosity present between the NiTi powders is infiltrated by an in situ created NiTi-Nb eutectic liquid which, after solidification,...
متن کاملRendering and Simulation of Liquid Foams
In this paper we present a technique for rendering and simulating liquid foams in real time using GPUs [11, 12]. The goal is to have bubbles meeting physical properties when interacting with each other and with other geometric objects such as planes and further giving a realistic geometric appearance, showing the detailed facet of intersecting bubbles. We achieve this using two rendering stages...
متن کاملStructure and energy of liquid foams.
We present an overview of recent advances in the understanding of foam structure and energy and their dependence on liquid volume fraction. We consider liquid foams in equilibrium for which the relevant energy is surface energy. Measurements of osmotic pressure can be used to determine this as a function of liquid fraction in good agreement with results from computer simulations. This approach ...
